KEY MESSAGES

- Narrow band of snow may result in light snow accumulation in our south this morning, largely in northeast MO.

- Wednesday through Thursday night will feature a few rounds of showers/storms, with a boundary that moves into the area and stalls out. Overall, most will see an inch or less of rain, with locations along the boundary seeing upwards to 1.50".

- Friday into Saturday will feature quieter weather with high pressure passing through. Then, a stronger wave will bring showers/storms to the area Sunday into Monday.

SHORT TERM /THROUGH TONIGHT/

Issued at 210 AM CDT Tue Apr 7 2026

Weak upper wave continues to pass through our south this morning, with a narrow band of frontogenesis just south of our area resulting in a band of rain/snow. LLVL moisture remains a limiting factor in precipitation, keeping it limited to our southern tier or two of counties. At this time, we are just starting to see more nearby obs indicating light precipitation, with dewpoint depressions in our south around 10-15 degrees still. Thus, plenty of dry air remains, resulting in light accumulation. Dense cloud cover has allowed temperatures to moderate around 40, rather than dropping below freezing. Thus, concerns for a freeze in those areas is low at this time. Also, temperatures above freezing should also allow melt of initial snowfall, further limiting accumulation. In the end, best chances for light accumulation will be along/south of a line from Keosaqua IA to Keokuk IA. Snow accumulation should remain around an inch or less, which has been highlighted in recent runs of CAMs, with possibly upwards to 2" in far southern reaches of Scotland and Clark County MO. Although, confidence in that is low at this time.

Through the remainder of the day, LLVL winds will shift southeasterly as the ridge slides east and allows return flow into the area. This will advect that band of frontogenesis north. This band will still lead to low-end chances (20-30%) for precipitation west of the Mississippi River through the morning. This afternoon and evening, we will see another weak bout of vorticity pass through the area, which would favor light precipitation again for the same areas. Temperatures at this time will have warmed into the low-mid 40s, favoring rain as the primary precipitation type, especially with elevated WAA. Thus, little impacts are expected from this. Rather, it will just keep conditions cool, cloudy, and unpleasant through the evening. Dense cloud cover will remain through the night, moderating temperatures in the mid- upper 30s. Although, a wave moving into the northern Plains will tighten the pressure gradient over the area tonight, resulting in increasing winds. While the winds will be out of the southeast, this will be a cool wind with temperatures in the 30s. Thus, bundle up for the Wednesday morning commute!

LONG TERM /WEDNESDAY THROUGH MONDAY/

Issued at 210 AM CDT Tue Apr 7 2026

Wednesday and beyond will feature quite the active weather pattern, with near-daily chances for precipitation within our forecast area. This active pattern can be attributed to LLVL southerly flow pumping into the area from the Gulf, increasing moisture throughout, with upper level zonal flow guiding weak disturbances off of the Rockies and towards our area. With that, a stalled out boundary will result in a few rounds of showers/storms Thursday into Friday. As we head into the weekend, upper level flow becomes more southwesterly due to a deep trof over the western CONUS, setting the stage for stronger waves Sunday and beyond.

Wednesday into Friday, we will see zonal flow aloft guide weak disturbances through the area, with a tight LLVL baroclinic zone progged to set up nearby. This pattern would favor the potential for rounds of showers and embedded storms. While some uncertainty exists on the placement of the boundary, global models favor this setting up somewhere over our forecast area. The bulk of the impacts from this setup will be seen Thursday into Friday. Although, prior, a deep wave will pass north of the area Wednesday night, dragging a cold front through the region. This cold front will not only bring the first round of showers/storms to the area, but it will eventually stall over the area, which will be the aforementioned boundary that will produce further showers/storms Thursday through Friday. Overall, the severe threat through this timeframe is low due to weaker forcing and instability. Rather, this will be more-so a rainfall event, with embedded thunderstorms. WPC favors much of the area seeing between 0.50-1.00" of rain through the end of the week, with a focused corridor of 1.00-1.50" where that boundary sets up. While this may sound like a washout, there will be plenty of dry time, especially Friday. Warmest temperatures this week will be seen on Wednesday, with widespread temperatures near 70. Cooler air will move in behind the front on Thursday for most of the area, with areas north of the front seeing upper 50s to low 60s and then south of the front remaining near/above 70. Friday will be cooler throughout, as the boundary finally gets pushed south and weak high pressure moves in.

High pressure and associated ridge push east Saturday into Sunday, with upper level flow becoming more southwesterly. This would favor strong WAA into the region, especially on Sunday. Saturday will serve as the transitional day, which should keep us largely dry with temperatures in the 60s. Going into Sunday, we see a more potent wave eject off of the southern Rockies and track northeast into the Central Plains. Surface low will follow a similar track, with leading shortwaves bringing chances for precipitation Sunday into Monday. Without a baroclinic zone stalled over the area, we are not expecting a focused area of heavy precipitation at this time. Rather, scattered showers and storms will result, especially with increasing instability. Too soon to determine any risk for strong/severe storms, but this will be the wave to watch, as it will have the better forcing and instability associated with it. Temperatures Sunday will be quite mild, with most of the area in the low-mid 70s.

AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/

Issued at 1201 AM CDT Tue Apr 7 2026

VFR conditions will prevail through the TAF period, with mid- high clouds largely resulting in overcast skies. Farther south, we will see lower cigs, but should remain >3kft at BRL. There will be low-end (<30% chance) chances for light snow/rain at BRL this morning, but confidence remains low. Thus opted to leave out of TAFs and will amend if necessary. Winds will start the TAF period out of the north around 10 KTs, gradually shifting southeastly by 18z. Otherwise, no sig wx is expected at this time.
